I think we have to include everybody, since there's no easy way to figure
out who's who.

I don't think I understand what you mean. If the "wrong" theory is a
rational choice, then we have an example where rationality has led us to
an incorrect conclusion. Rationality can never declare itself wrong,
however, so in order to evaluate it as "wrong" we would have to use some
*other* criteria for evaluating right and wrong besides reason. Any way
you slice this, it's at least non-rational, if not irrational.
